Solar flaring activity is gradually decreasing, with only one M1 (with peak at 13:20 UT) and eight C-class flares, mainly from NOAA active region 2422. NOAA 2422 is slightly decaying but still retains a complex magnetic configuration. NOAA 2427 has slightly grown, but did produce much activity. A series of CMEs were launched on September 30 of which at least two were related to a prominence eruption at the southwest limb. SDO/AIA and PROBA2/SWAP data indicate that solar material starts to lift late September 29/early morning September 30 and part of it falls back south and another part falls to the north. The southern part produces a CME with first measurement in LASCO/C2 at 10:00 UT and shortly after that the NW part produces a CME as well. These two CMEs visually merge later on. They mainly propagate to the West with a speed of 330 km/s (CACTus estimate), but it is not excluded that a glancing arrives at Earth late October 4. The CME activity did cause a rise in the proton flux (at >10MeV) to about 1pfu, though the flux values have not reached the event threshold. Proton flux values are gradually decreasing again. More C-class flares are expected, with a 25% chance for M-class flares.

The slow wind speed was low (with values around 300 km/s) till around 11 UT when the speed slightly increased to about 330 km/s. The phi angle has been varying from negative (towards) to positive (away) orientation. At 11 UT, the interplanetary magnetic field magnitude reached a peak of 10 nT. The geomagnetic conditions are quiet (K<3) to unsettled (K=3) and are mainly expected to remain so. There is a some chance for isolated time slots of active conditions (K=4).
